Quantum kinetic equations obtained from Zubarev's nonequilibrium statistical operator are used, and different initial effective temperatures for electrons and holes are taken. It is shown that holes relax their excess energy faster than electrons for all levels of photoexcitation, and that the mutual thermalization of electron and hole sub-systems depends on the degree of photoexcitation. The lapse of time for electrons and holes to attain mutual equilibrium is estimated to be of the order of 6 ps for a density of photoinjected carriers in GaAs of the order of n = 2.0 x 10(18) cm-3, when the initial excess of kinetic energy per pair is taken as 2.4 eV.
